Application mea March 2e, 191e. serial No. 757,026.

T 0 all whom it may concern Be it known that I, Pa'rnn G. SCHMIDT, a citizen ofl the United States, residing at Olympia, in the county of Thurston and State otwasliington, have invented a new and useful Gas-Producer, of which the following is a specification.

This invention relates to improvements in gas producers, and more especially to that type of producers known as rotary gas producers, the main object of the present invention being the provision of a means whereby rotary gas producers will generate and deliver from fuel having high volatile content, a much cleaner gas than is generally produced by this type of producer at the present state of the art, thereby increasing the thermal-efficiencyoi' the producer, making the cleaning of the gas much easier. and

also eliminating the necessity of disposing of large quantities of tar and other condensates from the gas.

The present inventionl in one form is applicable to the usual type of updraft rotary gas producer which has previously been provided with a centrally disposed depending gas collector, the present gas producer being designed to deliver a very much cleaner gas, causing less trouble from pipe and flue stoppage and consequently frequent shutdowns for cleaning; and. this also economizes in the apparatus, power and water for gas washing purposes in addition to giving the producer a high thermal efficiency.

A still further object of the present invention is the provision of means whereby thejusual form'of rotary gas producer has its field of operation and usefulness increased for especially the use of soft coals,

and for the purpose where the use of cleanl or washed gas is mandatory in contra-distinction to gasor smoke-gas application, to which application the existing modes of producers are practically limited when using fuel of considerable volatile content.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts .and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention. In the drawings Figure 1 is a vertical central sectional view of a rotary producer equipped with the present invention. Fig. 2 is an enlarged detail sectional view of a mechanically tight lubricated-sliding joint between the stationary and moving members of the air supplying means of the producer.

Referring to the drawings, the numeral l designates the base or supporting structure which is provided -with the ash reservoir 2 throu h which the ash is adapted to be removed iii-om the present reducer. An air conducting flue 3 is provldcd-upon the base and communicates with. the twyer 'or distributing chamber 5, the Same heilig provided with-the flattened conical top G, which is disposed in spaced relation to the upper edge of the chamber 5 so that air will be distributed to the circumferential space into the ash zone and the lower part of the fuel bed. This section 7 is provided with the outstanding -rim 8, which carries the water sealed receptacle 9 and is supported upon rollers 11 carried by the supporting posts 12-12. By this means the section 7 is permitted to be rotated relatively to the base 1 Peripheral 'teeth 13 are provided upon the outer surface of the water sealed-chamber 9 and mesh with the small gear 15 upon the vertical shaft 14, said shaft 14 being also provided with the large gear 16, said shaft constituting a means whereby the section 7, and upper section 17, as will presently appear, are rotated. The upper section 17 is provided with the outwardly projecting flange and supporting rim 18, which is disposed to rest upon a plurality of rollers 19 supported upon the posts 12 and 12', and thus provide anupper support fon the section 17, which is provided with the annular water chamber 20, which with Vthe apron 21 of the water cooled t0 or charging floor 22,

provides a water sea between the two so'- that asthe to 22 is rigidly and stationarily supporte through the inturned ends 23 and 23 of the supports 12 and 12,'the section 17 may be properly rotated. The flange 18 is provided with gear teeth 24, which mesh with the gearl, so that the up er section may be rotated.

ne or more coal or fuel inlets and hoppers 30 are provided, while the gas outlet 35 from the collector 33 is also provided. The usual poke holes 31, which are held tight by means of the lids or covers 32 are also provided.

Itis desirable that an auxiliary current.

lili

lil

ot air be supplied through the body of the fuel between the upper surface thereof, to assist in the gasication oit the distillate contained'therein. rllhereore in the structure shown, humidiiied air is vsupplied through the conduit to an annular chamber 26, the depending rims thereof being disposed within the liquid sealed chamber 27, which is connected to and rotatable with the section 17 through the vertical conduit 28, the outlets 28 of which are disposed to register with the nozzle 29, disposed within the peripheral openings 29 of the section 17. 'lhese openings 29 lead directly into the tuel magazine, so that the tendenc ot the air drawn therein will follow the irection ont the arrows shown in Fig. l through the body ot fuel into the inner end oir the gasV collector 33.

As shown in Fig. 2, the conduit 25' leads into the annular seating member 26 of the airdistributer, its llanges 26, fitting between the upstanding'danges 271 and 27b of the producer carried member 27. llhe anges 26b have their lower edges snugly seated in the member 27, while the spaces adjacent the danges 27 and 27 are to be lled with a lubricant. 'llhe pipe 28 leads from 'the member 27 to the nozzle 29 disposed in the opening 29 in the refractory wall or' the producer.

Vf hat is claimed is:

l. A gas producer, having a lower air inlet, a centrally depending gas collector, the

'inlener wall of the producer above the lower end of the collector being provided with means fori conducting auxiliary air thereinto, said means including an annular stationarily mounted memberhaving an extending rim in communication with an air supply, an inverted ring telescopically tting the same and lor-ming therewith a sealed joint, and conduits leading from the latter to the auxiliary airinlet of the producer.

2. A gas producer, having a revoluble fuel chamber section and a lower air inlet, a een trally depending gas collector projected into the tuel body, and means for supplying auxiliary air adjacent the periphery ofthe producer at a point above the lower end ont the gas collector and below the top surface of the fuel body, and consisting ot a humidied air conducting pipe, a telescopic water seal consisting oit' Itwo coacting members, one tiiredly connected tothe air conducting pipe and the other connected for rotation with the revoluble section, and a lurality ot nozales leading therefrom and t ough the wall of the sectlon at' a point above and in spaced relation to the lower end oil the gas collector.

lln testimony that ll claim the foregoing as my own, ll have hereto axed my -signature in the presence or two witnesses.
